Physical Properties of Ethanol

Ethanol, also known as ethyl alcohol or drinking alcohol, is a colorless and volatile liquid with a distinctive odor. It is commonly used as a solvent, fuel, and in the production of alcoholic beverages. Here are some key physical properties of ethanol:

1. State of Matter: Ethanol is a liquid at room temperature and atmospheric pressure.

2. Boiling Point: The boiling point of ethanol is approximately 78.37 degrees Celsius (173.1 degrees Fahrenheit) at atmospheric pressure.

3. Melting Point: Ethanol has a melting point of approximately -114.1 degrees Celsius (-173.4 degrees Fahrenheit).

4. Density: The density of ethanol is around 0.789 g/cm³ at 20 degrees Celsius (68 degrees Fahrenheit).

5. Solubility: Ethanol is highly soluble in water, forming a homogeneous mixture. It is also miscible with many organic solvents.

6. Odor: Ethanol has a characteristic, sweet, and slightly fruity odor.

7. Flammability: Ethanol is highly flammable and can easily catch fire when exposed to an ignition source.

8. Refractive Index: The refractive index of ethanol is approximately 1.361 at 20 degrees Celsius (68 degrees Fahrenheit).

9. Vapor Pressure: Ethanol has a relatively high vapor pressure, which means it evaporates easily at room temperature.

10. pH Level: Ethanol is a weak acid and has a slightly acidic pH of around 6.0 to 7.0.

It's important to note that these properties may vary slightly depending on the purity and concentration of the ethanol.
